introduced into Jamaica, I wrote to Dr. Alexander 
Garden, of Charles Town, South Carolina, to lend me 
fome of the joints of the Cadtus Opuntia, with the in- 
fedts on it; which he did the latter end of the year 1 757. 
Thefe fpecimens were full of the nefts of this infedt, 
in which it appeared in its various Rates from the 
moft minute, when it walks about, to the (late, 
when it becomes fixt, and wrapt up in a fine webb, 
which it fpins about itfelf. 
Thefe I had the honour to lay before the Royal 
Society, and afterwards, with a view to encourage 
the propagating and colledting them in our colonies, 
I exhibited the fame to the Society for encouraging 
Arts, Manufadtures, and Commerce, who chear- 
fully granted feveral large premiums ; the obtaining 
of which nothing can difappoint, but fcarcity of hands 
at prefent in our colonies. The Female (which was 
here alive and in plenty) is well difcribed by Monf. 
Reaumur, Dr. Brown of Jamaica, and lately by Dr. 
Linnaeus, in his Syftem of the animal kingdom, under 
the title of Coccus Cadti Coccinelliferi p. 457. n°. 17. 
from a living infedt fent him from Surinam by Mr. 
Rolander in the year 1756, but neither Reaumur, 
Brown, nor Linnaeus had ever feen the Male. 
As this genus of infedts is placed by Dr. Linnaeus 
under the Hemipterae or half winged, it may be ne- 
ceffary to know, that he comprehends in this clafs 
not only thofe, whofe wings are half covered with a 
cruftaceous cafe, but fuch alfo as have wings only on 
one fex. 
In order to find out the Male fly, I examined all 
the webbs in thefe fpecimens befides a larg« parcel, 
which the Dodtor had fent me picked off from the 
plants
